MBI-306, recently submitted to the EPA for regulatory approval, showed very positive results in 2021 corn and soybean field trials when evaluated for the control of top yield-robbing pests, corn rootworm and soybean cyst nematode.

The novel bioinsecticide/bionematicide is built on a proprietary microbe (Burkholderia rinojensis strain A396) that has been the active ingredient in MBI’s leading bioinsecticide, Venerate® XC, and Majestene® Bionematicide products. MBI-306 has shown to be non-toxic to humans, wildlife, aquatic life, earthworms and pollinators.

When tested as a seed treatment to control corn rootworm larvae, MBI-306 improved corn yields by up to 23 bushels per acre, a 14% increase when compared with untreated seed. The bioinsecticide also outperformed the leading commercial standard, delivering a 4% yield advantage. These yield gains equate to an estimated return on investment of $131 per acre versus untreated seed and $41 per acre versus current commercial products.

As a soybean seed treatment, MBI-306 increased yields by 11 bushels an acre, providing a 19% improvement and $130 per acre in additional revenue versus untreated seed. This novel bionematicide also showed excellent control with 6% higher yields when compared with commonly used treatments, providing growers an additional $47 per acre in returns.

When tested in-furrow, for control of corn rootworm larvae, MBI-306 showed an average yield advantage of more than 21 bushels per acre versus no treatment.
